the hot springs in japan and taiwan gives 20 for the 30min (1 hour for japan)
taiwan = is a hidden quest so it gives 20 the others gives 10
japan = 10 free and 10 when you pay 15 IM points (free pink/gold towel)
later rome is supposedly going to also get a pay spring so that should be another 10 for rome (free blue towel, not yet confirmed)
